Height of Bounce of a Squash Ball
Physics Department
==================
Experiment:
Aim: To investigate if a squash ball will bounce higher than its
average room temperature bounce, once the temperature inside of the
ball has increased.
Prediction:
I predict that the ball will bounce higher than its average room
temperature height once the temperature inside the ball has increased
Hypothesis:
I predict that the ball will bounce higher once it is heated because
when the temperature increases, the gas inside the ball will too. The
lower the pressure of the ball is, the easier it will change shape.
When there is low pressure, the ball is deformed by the energy it uses
when it hits the floor. The volume of the ball increases in pressure
once again.
Then the ball will reshape to its normal round shape as the pressure
increases in order to make it push off the ground.
When the ball is heated, the molecules will vibrate faster causing the
atoms to hit the sides more, and the ball will have a higher pressure
and a harder, more rigid ball because of the increase in the volume,
(The volume is proportional to the pressure). The height of the ball's
bounce will increase because of the amount of lift increase that the
ball produced once it hits the floor, thus making the ball go up.
Plan:
1. First you must set up a clamped ruler that is in a vertical
position.
2. Someone must drop
3. We have to drop the ball from the top of the ruler to the bottom
while our partner measures its bounce from the bottom of the ball.
4. We record our results from a ball at room temperature.
5. Then we gradually increase the temperature of the ball from room
temperature by heating it in a water bath and recording the results
and at a temperature increase at 10°C every-time, then bouncing the
ball to aid our experiment results.

How does the material of a ball affect the bounce height/vertical motion of that ball?
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested.
